Summer heat and humidity cause folks to think about escaping to swimming pools, lakes, mountain retreats, and beaches. If your home is your sanctuary, then find refuge in your garden with our native summersweet (Clethra alnifolia). This month, summersweet produces spikes of spicy, fragrant flowers atop a 4 to 8 ft. high multistemmed shrub with attractive lustrous green leaves. The flowers mature into clusters of woody capsules that look like dried peppercorns. In the fall, summersweet leaves turn pale yellow to rich golden yellow.
